What is a percentile rank, and what does it mean?

Percentile identifies the percentage of a group, in this case hospitals, that an individual hospital’s score is better than. For example, a hospital’s patient satisfaction score with a percentile rank of 73 means that hospital’s score is higher than 73% of the comparison hospitals. For HCAHPS, the comparison hospitals may be made up of other hospitals that use Gallup or the HCAHPS survey (about 4000 hospitals).
